I bought a cheapy 64 GB SSD just for putting a pagefile on it, since I did not want my expensive Intel SSD's in RAID 0 getting pounded by a page file.
There is another option that I highly recommend - use Diskeeper. The software will adapt to pretty well all environments. It is most effective on "standard" hard discs, but is still very very effective on SSDs - as a parallel illustration, 100% effective on standard hard disks, and 98% effective on SSDs. Don't be put off by the 2% (!) - that's only my way of illustrating how good it is, and the fact that it can deal with all disc technologies.
It will intercept a call for information on disc, and if its in the cache, provide that instead - there is much much more to it than that, don't jump to any conclusions with that crude explanation. However, I have used Diskeeper since its inception many years ago, and it hs grown massively - many top flight Corporates use it as an essential Core Systems Tool. It is effective with single machines, as well as huge Networks. There is much more to it than a "mere" cache, don't jump to conclusions.
It has three main modes that it uses simultaneously, automatically selecting the best one for the task in hand at any instant (numbers in brackets are taken directly from my 3960x with a 4480Gb SSD Drive C, and a 1Gb standard hard disk drive D) as a measure of disc accesses prevented:
- Prevented by IntelliWrite - 100% (22,500 fragmentations handled in 24 hours)
- Eliminated by instant defrag - 0%
- Eliminated by Defragmentation - 0%
Total Disk I/O's saved - 1,376,704
Bottom line ..... it rarely has to take anything from the hard disk, and drastically reduces I/O useage. Disk speed access and throughput improvement is very significant. Frankly ..... run don't walk to get it. Its not cheap ..... but after initial purchase, it settles to around £48 maintenance a year. This is Major Corporate level software now, so be clear its stable and reliable. Despite the latter, its still effective on PCs at a personal level (that's its original routes many years ago).
It is very aware of SSDs, and will automatically curtail some "optimisation" routines than happen on standard Hard Discs, to prevent it accessing the SSD - fragmentation clearly not being an issue all with SSDs, so it just leaves it alone in that regard - the latter is the bottom line, it is massively effective not only in speed enhancement, but also in ensuring your SSDs are not pounded reducing SSD life.
Its memory needs are minimal, and there is negligible drag on the Processor. Being - now - use by many many Corporates on their Global Networks, its also very reliable. Run don't walk to get it
